Passive motion apparatus providing a controlled range of motion

A passive motion apparatus for providing passive motion of the lower trunk and legs of a user relative to the remainder of the body of the user, said apparatus comprising:

• a first elevated support member for, in use, supporting, a rear portion of the upper trunk of a user and back portion of the head of the user;
• a second elevated support member, movable with respect to said first support member, and disposed at a common level with, and adjacent to, said first support member, for, in use, supporting, buttocks down, the lower trunk of the user;
• a third elevated support member, disposed in a plane elevated with respect to said common level and disposed adjacent to said second support member, for supporting the lower portions of the legs of the user so that, in use, the upper leg portions of the user extend at substantially 90° to both the lower trunk of the user and the lower portions of the legs of the user;
• and
• means for, when activated, providing continuous cyclically repeated pivotable movement of said second support member about a vertical pivot axis between first and second end positions so as to provide continuous passive motion of the lower trunk of the user.

A passive motion apparatus, said apparatus comprising:

• a main support assembly for supporting at least part of the body of a user of the apparatus and including a first support member including a substantially horizontal support surface defining a first plane and a second support member including a substantially horizontal support surface disposed in said plane, said second support member being pivotably connected to said first support member and being movable relative thereto such that movement of the second support member with respect to the first support member provides passive movement of a part of the body of a user supported by said second member relative to a part of the body supported by said first support member;
• a first, separable leg support assembly adapted to be connected, in use, to said main support assembly at either end of said main support assembly so as to support at least part of the legs of the user in a second plane elevated with respect to said first plane;
• a further, separable leg support assembly, for use when said first leg support assembly is not being used, said further leg support assembly comprising a leg support member defining an upper support surface and adapted to be connected, in use, to said main support assembly such that said upper surface of said leg support member is disposed substantially in said first plane;
• and
• motorized drive means for, when activated, providing continous cyclically repeated movement of said second support member relative to said first support member.

A passive motion apparatus for providing passive motion of the lower trunk and legs of a user relative to the remainder of the body of the user, said apparatus comprising:

• a body support unit comprising:
• a first support member for, in use, engaging the upper trunk and head of a user;
• a second support member, movable with respect to said first support member and disposed adjacent to said first support member, for, in use, engaging the buttocks of the user;
• a third support member, disposed adjacent to said second support member in a different plane therefrom, for engaging the lower portions of the legs of the user so that, in use, the upper leg portions of the user extend at substantially 90° to both the lower trunk of the user and the lower portions of the legs of the user;
• and
• motor means for, when activated, providing continous cyclically repeated lateral pivotable movement of said second and third support members relative to said first support member;
• and
• a stationary base for pivotably supporting said body support unit so as to enable pivoting of said body support unit between a first, substantially vertical position wherein a user is supported in seated posture on said body support unit and a second, substantially horizontal position wherein a user is supported in a reclining posture on said body support unit.

A passive motion apparatus, said apparatus comprising:

• a main support assembly for supporting at least part of the body of a user of the apparatus and including first, second and third support members for supporting different parts of the body of the user, at least one of said support members being pivotably mounted and being movable relative to the remaining support members of the main support assembly such that movement of the at least one support member with respect to the remaining support members provides passive movement of a part of the body of a user supported by said at least one member relative to a part of the body supported by the remaining support members;
• a leg support assembly connected to said main support assembly at one end of said main support assembly so as to support lower portions of the legs of the user in an elevated plane relative to said main support assembly such that the lower portions of the legs of the user are elevated with respect to the remainder of the body of the user and upper portions of the legs of the user extend at substantially right angles to the lower portions;
• and
• motorized drive means for, when activated, providing said movement of said at least one support member relative to said remaining support members on a continuous, cyclically repeated basis to provide continuous passive movement of the part of the body supported by said at least one support member;
• one of said support members of said main support assembly including cervical rotation means for, when activated, providing continuous, cyclically repeated, rotational movement of the neck and head of the user.
